New Slot Site of the Month

You won’t believe it - we're back at the pub for our "Site of the Month" feature! Don't worry; I’m completely sober and made this pick with a clear head. So, without further ado, our favourite new slot site is... Pub Casino! But why, you ask, did I choose this new site to raise a glass to? Well, let’s dive in and find out!

There is a new games section with slots like Release The Kraken Megaways, Tomb of Gold, and Happy Fortune Dragon.

• Easy to find and wager on the best new slots.
• You can use the welcome bonus on most slots.
• A mix of the best game providers, such as Red Tiger, NetEnt, Play'n GO, and Microgaming.

Dive right in with our slots calendar, crafted to ensure you never miss a new release. It displays the current month, and each casino slots provider is colour-coded to highlight their upcoming titles. Clicking on a date opens more information on the titles set to drop that day.

I might be biased, but there’s no better way to stay on top of new releases than by keeping a close eye on this slot calendar. Whether it's a new slot game or a new site with exclusive offerings, it’s sure to leave no stone unturned.

Each demo includes a full review from me or one of our experienced slot testers, giving you all the information you need before playing.

Knowing about the big new thing before anyone else is always fun. If you’re anything like me, it’s no different with brand new online slots. Being the first to discover the top trending slots is worth celebrating, especially when you can share your tips with fellow fans.

Here are five top slots to keep an eye on right now:

The world of online slots never stops growing and changing. You have more brand new slots to choose from than ever, with new themes and tweaks to the technology dropping all the time.

Ok, let’s have some real talk. Slots are all about chance and luck. It’s not like playing poker when reading up on tactics and honing your craft at the table boosts your chances of winning. With slots, it’s all on the luck of the draw – that’s why we talk about a poker face, but not a slots face. 

But you can be tactical with how you play slots. These are my top tips that’ll ensure you always play online slots the smart way.

If you love slots, you’ll love a free spins promo. These do exactly what you expect: you get to spin for free, and if you win, it’s all on the house. Sign up as a new member, and the casino will dish out some free spins that align with their welcome offer. It’s such a crowded marketplace with so much competition, so shop around for the best free spins offers. 

But as we all know, you don’t often get something for nothing. And it’s the same with free spins. Most online casinos expect you to make a small deposit before claiming free spins - usually around £10 or £20. When you play your spins, you don’t tap into this deposit, and if you win, real money drops into your cash pot on the house. 

The Holy Grail is free spins with no deposit – it’s widely adored but rarely found. Also, keep your eyes out for weekly or daily free spin offers. 

Here are three of the best free spins promos to claim right now: 

When a new slot drops, it’s all about drumming up some excitement around the game. And one of the most popular ways is with a slot tournament. So, if you like your prizes big and enjoy a social element to your gaming, always check them out.

Entry is almost always free, with the potential for massive prizes. You might just need to deposit using a bonus code, though. Plus, you'll compete against players from all over the world, with message boards and live chats adding plenty of banter and fun.

One of your first ports of call when playing new online slots is to check the RTP of each game. What’s RTP, I hear you ask? Let’s get into it. The RTP is the theoretical amount you’ll win when you play the game over a longer time. Every online slot has one, and we like to list them to help you.

An RTP of 94.75% means that for every £100 bet, the slot would payout £94.75. But remember, it’s all theory. If you spend £100 overtime on the same game, there’s no guarantee of £94.75 arriving to your bankroll. That share of money is being paid out to players, but there’s no promise it’s coming to you. Games with a higher RTP offer a better deal. In theory, they pay back more money in winnings to players – including you.

We’ve seen it before. You see the words ‘progressive jackpot’ and run for the hills. But stop, think, and get ready to climb that hill. 

With progressive jackpots, the online slots bonus and your winnings can be huge. We’re talking massive seven or eight-figure sums. The odds of winning may be lower, but it's always worth holding back some cash in hopes of taking home that massive jackpot.

The new slots with the biggest jackpots at the time of writing are:

• WowPot slots - £35m
• Mega Moolah - £8.7m 
• Jackpot Giant - £6.2m 
• Dream Drop slots - £2.5m
• MegaJackpots slots - £1.1m
• Mega Fortune - £0.8m

If you’re keen to start playing some new online slots, here’s a step-by-step on how to get the ball rolling.

1. Choose any online casino we recommend. We’ve listed many on this page, including brand new casino sites. They're licensed and regulated - we’d never promote a site that isn’t. 
2. Create an account. Click the link on this page and start the signup process. Create a username and password. Then, share personal details like your name, address, and birth date. Either now or later on, the site will need to verify your identity by sharing a government-issued ID.
3. Deposit. Each site will detail online casino payment methods. Pick your one and enter the amount you’d like to deposit – select the minimum amount needed to unlock any free spins. Your bonus will either get added automatically, or you’ll need to enter a code. We’ll share the code on Casinos.com wherever you need it.  
4. Install any apps. Most casinos have apps for iOS and Android. Set them up now.
5. Play! Find your favourite new slot in the lobby. Check your free spins are in place and get into the action. 

That’s all. The world of new online slots awaits.
